Let P be the transmission rate of the j-th vehicle in the first communication link list. cir Let K be the first total power consumption, and K be the total number of vehicle terminals in the first communication link list. This represents the first transmit power of the j-th vehicle in the first communication link list under the multiplexing model.

[0040] S3: Obtain the second communication link list; the second communication link list includes multiple vehicle-to-vehicle communication second communication links; the vehicle-to-vehicle communication is a signal transmission communication that reuses the vehicle terminal and other vehicle terminals.

[0041] The second communication link is V2V link 1, which refers to a vehicle-to-vehicle communication link, specifically the communication link between vehicle terminal 2 and other vehicle terminals 2. In this example, it refers to the communication link with the lowest power consumption when multiplexing vehicle terminal communication with other vehicle terminals. The list of second communication links can be a list constructed based on the second communication links, and each second communication link in the list corresponds to a multiplexed vehicle terminal.

[0045] The second target energy efficiency of the reused vehicle is obtained using the following formula:

[0047] in, The second target energy efficiency is for the i-th vehicle in the second communication link list. Let P be the transmission rate of the i-th vehicle in the second communication link list. cir ′ represents the second total power consumption, and M represents the total number of vehicle terminals in the second communication link list.

[0048] S5: Based on the first target energy efficiency and the second target energy efficiency, obtain a first target energy efficiency selection priority list and a second target energy efficiency selection priority list for each multiplexing vehicle terminal; the first target energy efficiency selection priority list is used to indicate the energy efficiency priority of the multiplexing vehicle terminal corresponding to the first communication link in reusing the second communication link; the second target energy efficiency selection priority list is used to indicate the energy efficiency priority of the multiplexing vehicle terminal corresponding to the second communication link in reusing the first communication link.

[0049] Please see Figure 3 Step S5 may include:

[0050] S51: Construct an energy efficiency table based on the first target energy efficiency, the second target energy efficiency, and the corresponding shared vehicle end.

[0051] like Figure 3 As shown in the energy efficiency table, m1 represents the communication link between the first multiplexed vehicle terminal in the first communication link list and the base station, k1 represents the communication link between the first multiplexed vehicle terminal in the second communication link list and other vehicle terminals, m1 and k1 correspond to the same multiplexed vehicle terminal, P represents the energy efficiency priority of the multiplexed vehicle terminal corresponding to the first communication link list in reusing the second communication link, and Q represents the energy efficiency priority of the multiplexed vehicle terminal corresponding to the second communication link list in reusing the first communication link.

[0052] S52: Based on the energy efficiency table, obtain the first target energy efficiency selection priority list and the second target energy efficiency selection priority list for each reused vehicle.

[0053] In step S52, the first target energy efficiency of the reused vehicle is sorted in the energy efficiency table according to a preset order to obtain a first target energy efficiency selection priority list. Similarly, the second target energy efficiency of the reused vehicle is sorted in the energy efficiency table according to a preset order to obtain a second target energy efficiency selection priority list. Therefore, both the first and second target energy efficiency selection priority lists can be represented as sets, such as the first target energy efficiency selection priority list being {Pm}. i ,k j The priority list for selecting the second target energy efficiency is {Qm} i ,k j}

[0054] S6: Based on the first target energy efficiency selection priority list and the second target energy efficiency selection priority list, obtain the multiplexed communication link based on the target multiplexed vehicle terminal; the multiplexed vehicle terminal is a vehicle terminal used for both base station-vehicle terminal communication and vehicle terminal-vehicle terminal communication.

[0055] Step S6 refers to allocating communication resources to the target reuse vehicle according to the first target energy efficiency selection priority list and the second target energy efficiency selection priority list, so as to obtain the reused communication link.

[0056] Compared to related technologies, this application obtains a first target energy efficiency for each multiplexed vehicle terminal based on the first transmission rate of each multiplexed vehicle terminal corresponding to the first communication link list for base station-vehicle terminal communication, the first transmit power of each multiplexed vehicle terminal under the multiplexing model, and the first total power consumption of all vehicle terminals. It then obtains a second target energy efficiency for each multiplexed vehicle terminal based on multiple second transmission rates of each multiplexed vehicle terminal corresponding to the second communication link list for vehicle-to-vehicle terminal communication, the second transmit power of each multiplexed vehicle terminal under the multiplexing model, and the second total power consumption of all vehicle terminals. Based on the first and second target energy efficiencies, it obtains a first target energy efficiency selection priority list indicating the energy efficiency priority of multiplexed vehicle terminals in multiplexing the second communication link corresponding to the first communication link list, and a second target energy efficiency selection priority list indicating the energy efficiency priority of multiplexed vehicle terminals in multiplexing the first communication link corresponding to the second communication link list. Finally, it allocates communication resources for the multiplexed vehicle terminals based on the first and second target energy efficiency selection priority lists, enabling the multiplexed vehicle terminals to be used simultaneously for base station-vehicle terminal communication and vehicle-to-vehicle terminal communication, thereby obtaining multiplexed communication links based on target multiplexed vehicle terminals. Because this application combines the transmission rate and transmit power of the target multiplexing vehicle terminal in the first communication link list and the second communication link list to obtain the first target energy efficiency selection priority list and the second target energy efficiency selection priority list, the resulting multiplexed communication link based on the target multiplexing vehicle terminal takes into account both the transmission rate and transmit power parameters, so that the multiplexed communication link can achieve both high speed and low power, thereby improving the energy efficiency of the communication resources allocated in the vehicle network.

[0057] In a feasible embodiment, step S5: obtaining the multiplexing communication link based on the target multiplexing vehicle end according to the first target energy efficiency selection priority list and the second target energy efficiency selection priority list, includes:

[0058] S51: Based on the target second communication link and the second target energy efficiency selection priority list, obtain the connection invitation and the target multiplexing vehicle terminal corresponding to the connection invitation;

[0059] The target second communication link is a link that needs to be allocated multiplexed communication resources, such as a second communication link that has failed to be allocated or has not been successfully established as a multiplexed communication link.

[0060] S52: Based on the first target energy efficiency selection priority list, obtain the temporary matching link initiated by the target reuse vehicle terminal for connection.

[0061] Among them, the temporary matching link is the second communication link with the highest priority matching degree in the first target energy efficiency selection priority list for the target reuse vehicle.

[0062] S53: The multiplexed communication link is obtained based on the connection invitation and the temporary matching link.

[0063] The multiplexed communication link includes a target multiplexed communication link; step S53: obtaining the multiplexed communication link based on the connection invitation and the temporary matching link includes:

[0064] S531: If the invitation matching link matched according to the connection invitation corresponds to the temporary matching link, the target multiplexing communication link is obtained according to the target multiplexing vehicle terminal and the first target communication link.

[0065] S532: If the invitation matching link matched according to the connection invitation does not correspond to the temporary matching link, the invitation matching link is determined as a temporary multiplexed communication link.

[0066] Among them, the priority of the temporary multiplexing communication link is lower than that of the target multiplexing communication link. Therefore, when both the target multiplexing communication link and the temporary multiplexing communication link involve the same second communication link or the target multiplexing vehicle end, the temporary multiplexing communication link is abandoned and the target multiplexing communication link is retained.

[0067] In this embodiment, for example, using V2V link k j For example, V2V link k j Based on the second target energy efficiency selection priority list, the vehicle m with the highest priority list value is selected for reuse. i Send an invitation to establish the first target communication link; specifically, the target multiplexing vehicle m i There is a limit to the number of invitations. When the maximum number of invitations is reached, the target reuse vehicle m will be restricted. i Reject link k j The invitation can also include k j Add to the rejection list; when the invitation limit has not been reached, the target reuse vehicle m i From the first priority list for energy efficiency selection, the second communication link with the highest priority matching degree is selected for temporary matching, resulting in k. j →m i Temporary matching link, if the target reuse vehicle m i Receive invitation and link k j Successful match yields m i →k jWhen the two-way matching is stable, the temporary matching link corresponds to the invited matching link, and a multiplexed communication link can be obtained based on this correspondence. If the temporary matching link does not correspond to the invited matching link, the invited matching link is determined as the temporary multiplexed communication link. A stable, high-speed, and low-energy-consumption multiplexed communication link can be obtained through two-way matching.
